GEOLOGY

Detailed explanation-1: -Intensity scales, like the Modified Mercalli Scale and the Rossi-Forel scale, measure the amount of shaking at a particular location. An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are.

Detailed explanation-2: -The Modified Mercalli Intensity (MMI) estimates the shaking intensity from an earthquake at a specific location by considering its effects on people, objects, and buildings.

Detailed explanation-3: -It measures the effects of an earthquake at a given location, distinguished from the earthquake’s inherent force or strength as measured by seismic magnitude scales (such as the “Mw” magnitude usually reported for an earthquake).

Detailed explanation-4: -The Modified Mercalli scale measures the earthquake’s effect on people, property and ground damage. Roman numerals are used to rate the intensity and damage. An earthquake may have a different intensity rating at different locations. Damage is usually lessened with distance from the earthquake’s epicenter.
